Does your coolant heater also circulate the coolant?
If so you might want to consider how much heat you lose through the night from the radiator fins.
If you're going to be checking under the hood in the mornings anyway, then you might consider putting a couple of large ball-valves on your main radiator hoses . If your heater circuit dumps to the heater-core return line and goes directly back to the radiator ( like some cars do ), then of course you'd have to splice the heater-core return to another area on the engine-side of the ball valves, - not the radiator side.
I just thought I'd throw that idea out there, and I hope it was understandable.
It's an immersion heater in the block. It's not a circulating heater per se, although I'm sure some natural circulation takes place. I don't think there should be too much heat loss through the radiator, because the thermostat is closed so I don't think there would me hardly any circulation out to the radiator. Frankly, I'm not sure where the heater core returns the coolant.
